5 Claims.

This invention relates to dishwashing machines and in particular-to means whereby the ordinary standard kitchen sink may be converted to a dishwasher.

To date it has been the practice toprovide dishwashers either as a unitentirely separate from the kitchen sink or as a unit formed adjacent the kitchen sink but integral therewith. In both instances special equipment is required the cost of which is beyond the means of the average individual.

In general the object of my invention is the provision of means whereby any sink and in particular any standard kitchen sink can be made to' perform both its normal'iunction as well as the function of a motor drivendishwasher.

More specifically the object of the invention is the provision incombination with a sink, and a rackdisposed therein, of a deformable fabricated hood adapted to cover the dish rack and its load and to conform about the ordinary obstructions associated with the sink such as faucets etc.

Another object of the invention is the provision of means whereby the hood used to cover the sink and its load may be detachably and effectively sealed to the sink.

Still another object of the invention is the provision of means whereby watermay be introduced through the hood into the water circulating systern within the sink, in advance of the point where the circulating system contacts the load therein.

The invention possesses other advantageous features, some of which with the foregoing, will be 'set forth at length in the following description where that form of the invention which has been selected for illustration in the"drawing accompanying and forming a part of the present specification is outlined'in full. In said drawing, one form of the invention is shown, but it is to be understood that his not limited to such form, since the invention as set forth in the claims ma be embodied in a plurality of forms.

Referring to the drawing:

The single figure is a vertical section taken through a standard sink and in which the objects of my invention have been embodied.

As shown in the single figure'the sink I has secured to its base-by any suitable means a motor 2 which drives an impeller 3 The impeller may be made to extend either through the usual drainage opening provided inxthe sink or aseparate opening for this purpose may becut in the sink.

Disposedwithin the. sink is a dish rack 4 providedwith legs adapted to rest on the floor of the sink. Y I

Secured between two annular metal bands 6 and l is a deformable rubberized'hood 8 provided at its upper portionwith a water intake 9 adapted to register with the upper outwardly flaring end of a pipe I 0 supported by or secured to the silverware compartment ofthe dish rack 4. The lower end of the pipe [0 terminates directly above the impeller 3 and it will'therefore be seen that by running a, hose from the faucet II to the inlet 9 clean water may be supplied to the impeller '3. As an alternative method of introducing water into the sink an intake can be provided through adapted when wet to adhere to the inner 'walls' of the sink. An annular skirt l3 weighted" by suitable weights M is also secured to the peripheral edge of the hood and serves to hold the band l2 against the inner sloping walls of the sink I v thereby serving to seal the lower edge of the hood to the sink walls. To the band 6 is secured a number of spaced brackets IS the free ends of which are formed into hooks adapted to engage the ring l8 of the rack 4 and to thereby detachably support the hood 8 from the rack 4. The hood 8 is preferably made of a rubberized material and at all events should'be made of a deformable or flexible materiaLso that it may readily conform about the faucets I! as clearly shown in the drawing and about any other obstruction associated with the sink such assoap containers. This feature is of great importance for although kitchen sinks are standardized to some extent, there is a great variation in the type of faucets used and in their location. This discrepancy in the type. and location of the faucets isof course immaterial when'a flexible hood is well as the action of steam and boiling water.

In operation the rack 4 together with its load is placed within the sink. The hood 8 is then placed over the rack and its load and supported by means of the brackets I! on the ring i6 as above described. Water and chemicals may then be introduced into the sink either by means of the inlet 9 provided in the hood or by means of nozzles such as shown in the Snyderpatent above referred to and preferably in advance of the point at which the cleansing water contacts the dishes in the rack. When the motor 2 is set into operation the impeller 3 throws a spray of water upwardly against the dishes and with sufficient force to inflate the hood 8 to a certain extent. When the dishes have been washed and rinsed the .water may be drained from the sink either by means of a drain associated with the casing of the motor as shown in the drawing or by means of a separate drain provided in the sink.

From the above disclosure it will be seen that I have provided means whereby a standard kitchen sink maybe utilized as a dishwasher irrespective of the type of sink used and irrespective of the type and location of the faucets or other obstructions associated with the sink. It will also be seen that in using a flexible or deformable hood the problem of storage has been overcome, together with the problem of sealing to any sink.

I claim: a

,1. In combination: a sink; a motor driven impellr secured adjacent the floor oi the sink and a dish rack disposed therein; a pliant hood detachably secured to and supported by said dish rack; and means for sealing said hood to the sink.

2. In combination; a sink; a motor driven impeller secured adjacent the floor of the sink and a dish rack disposed therein; a deformable hood,

detachably secured to and supported by said dish rack; and means comprising a weighted flexible skirt associated with the peripheral edge of the hood ior sealing the hood to the sink.

3. In combination: a sink; a motor driven impeller secured adjacent the floor oi the sink and a dish rack disposed therein; a deformable hood detachably secured to and supported by said dish rack; and means comprising a relatively thin band of flexible material secured to the peripheral edge of the hood and adapted when wet to adhere to the sink to thereby seal the hood to the sink.

4. In combination: a sink; a motor driven impeller secured adiacent'the floor of the sink and a dish rack disposed therein; a deformable hood detachably secured to and supported by said dish rack; and means for sealing the hood to the sink comprising a relatively thin band of flexible material secured to the outer peripheral edge of the hood and adapted when wet to adhere to the sink; and a weighted skirt associated with the inner peripheral edge of the hood for holding said thin band against the walls of the sink.

5. A dishwasher comprising a sink; a motor driven impeller disposed in the base of the sink;

a hood adapted to cover said'sink; an inlet in said hood; a basket within the sink; and a conduit-
